Advanced Heating and Cooling Systems in Hybrid Electric Vehicles (HEVs)

This Advanced Heating and Cooling Systems in Hybrid Electric Vehicles (HEVs)Presentation was developed through a seed grant from the Center for Advanced Automotive Technology (CAAT) and discusses the advanced air conditioning systems placed in HEVs, and safety precautions to follow when servicing them. These systems are high voltage A/C compressors and the components controlling them (A/C ECU, HV ECU, and Converter Control Circuit). Safety precautions discussed include Class 0 insulated gloves, insulated tools, color coding of wire looms to indicate voltage, CAT III and IV multimeter use, and properly disabling high voltage circuits. For educators looking to modify current courses, a syllabus is also included with highlighted fields where HEV systems and safety were incorporated into an existing automotive heating and cooling course at Lewis and Clark Community College.
